- Don't forget to always scout. After your first burst drone died, you were playing blind for a while.- Value your units more. You had 4 tengus lang against 6 tengus and a turret. No way you're gonna kill anything and you lost them for nothing. If you scouted a little, you would have seen blue's 3rd ref = easy kill.- Along the same lines, harass effectively and defend harassment. They got your partner with a turret push and your 3rd ref with a ST. Both are easily counterable. And you could have done the same thing to them. So be aware that this game is more than just massing units and having a giant battle.- Lastly, help your partner. You had a bunch of tengus and VXs doing nothing while he was getting pushed. This is one of the biggest differences between 1v1 and 2v2/3v3. In 2v2, teamwork >> 2 simultaneous 1v1s.

I'd say the two biggest things by far were scouting and keeping your units alive (which are kind of related). For example, don't leave your burst drone hanging around the middle of his base for long, because eventually he'll find something to kill it. It's less likely to die if it's slightly to the side, hard to see or something like that. Later in the game, you can use tengus to scout.

Also, you might consider putting 1 or 2 IWs in garrisons if they're untaken, since that gives you visibility. And you could consider taking observation posts. It's an investment, but if you're having trouble scouting, that could be one way to help/practice.
